1. Find the area of a house-shaped figure made of a rectangle (6m × 4m) with a triangle on top (base 6m, height 3m).

2. Calculate the area of an L-shaped figure made of two rectangles: Rectangle A (8cm × 5cm) and Rectangle B (3cm × 4cm).

3. A composite shape consists of a rectangle (10m × 7m) with a right triangle attached to one side (base 4m, height 7m). What is the total area?

4. Find the area of a shape made from a square (side length 8cm) with an isosceles triangle on top (base 8cm, height 5cm).

5. A T-shaped figure is made from two rectangles: the top rectangle is 12m × 3m and the bottom rectangle is 4m × 8m. Calculate the total area.

6. Calculate the area of a pentagon made from a rectangle (9cm × 6cm) with a triangle cut from one corner (base 3cm, height 2cm).
